This is a national stage filing in accordance with 35 U.S.C. §371 of PCT/US2012/036115, filed May 2, 2012, which claims the benefit of the priority of U.S. Provisional Patent Application No. 61/481,537, filed May 2, 2011, entitled, “Strength Training Aid”, the contents of which are incorporated herein in their entirety.

FIELD OF THE INVENTION

The present invention relates to the field of strength training devices, and in particular to a device that develops strength in the forearms, upper arms and shoulders. The present invention enables an individual to increase his/her strength and ability to participate in various sports.

BACKGROUND OF THE INVENTION

There are various devices for strengthening the hands, wrists, forearms, upper arms, back and shoulders. These devices operate on the principles of variable threading, tension, torque, and compression mechanisms. These devices range from simple spring like devices which are operated in one hand such as free weights to complicated machines which can develop multiple muscles and muscle groups simultaneously. Strength training devices are currently available for everyone from the casual athlete to the professional athlete. The strength training devices which the professional athletes use are usually complex, relatively expensive, and generally not available for the average person/athlete. Another problem with the strength training equipment that professional athletes use is that it is designed for a specific sport. An individual who wants to play multiple sports would need to purchase many different pieces of strength training equipment.

DESCRIPTION OF THE PRIOR ART

U.S. Pat. No. 5,709,637 discloses a portable exercise device for specific strength training of the rotator cuff. The device includes a cylindrical spool which has a handle across its diameter. A length of elastic tubing is secured tangentially to one point of the spool. The opposite end of the elastic tubing is securable to a fixed point or object. This permits an individual to grip the handle and rotate or move the spool against a continuous resistance for muscle development.

U.S. Published Patent Application No. 2002/013599 discloses a strength training device for developing the forearms, upper arms, and shoulder muscle groups. The device includes two cylindrical handles with fixed concave surface end caps that are connected by a cylindrical center joint piece. The center piece has a concave surface on top and an under body cavity on the bottom. One end of an exercise cord is secured to the center joint piece. The opposite end of the exercise cord is secured to free weights. The free weights are raised and lowered by an individual rotating the cylindrical handles toward their body and away from their body. Weight machine cables can also be secured to the center joint piece. This enables an individual to perform bicep curls and triceps extension exercises.

Therefore, there is a need in the strength training art to provide a device which is portable, adjustable, and easy to use. The training device should be relatively simple in construction and portable for easy transport and use at remote locations. The device should also be capable of adjustment for athletes having a range of strength ranging from beginning amateurs to professional athletes. The device should also be adaptable for use by athletes training for various sports without the need for complex tools or scores of auxiliary parts.

DETAILED DESCRIPTION OF THE INVENTION

While the present invention is susceptible of embodiment in various forms, there is shown in the drawings and will hereinafter be described a presently preferred, albeit not limiting, embodiment with the understanding that the present disclosure is to be considered an exemplification of the present invention and is not intended to limit the invention to the specific embodiments illustrated.

FIGS. 1-4, which are now referenced, illustrate one embodiment of the present invention and the manner in which it is assembled. In general, thestrength training device10 comprises a hollowtubular member12, atraining object14 removably secured to one end of the hollowtubular member12, and afastening device16 secured to an opposite end of the hollow tubular member. More specifically, the hollowtubular member12 is preferably made from a flexible, non-elastic material such as a reinforced rubber and may includevarious filler materials13 which vary the weight and action provided by the tubular member. For example, sand alone may be added to give one weight and a relatively dead action to the tubular member. Alternatively, a filler such as steel shot may be combined with rubber particles or beads to result in a different weight and substantially more action provided by the tubular member. Various other combinations of materials may be added singularly or combination to allow the athlete to tailor his training to his particular needs. In this manner, the athlete may train for strength, speed agility, dexterity and the like with a single training tool by altering its properties. In the embodiment illustrated inFIGS. 1-4 thetraining object14 is illustrated as abaseball30 is secured to one end of the hollow tubular member. The ball may be directly adhered to the tubular member as illustrated inFIG. 2 or alternatively and preferably, a swivelingquick release coupling20 may be provided to allow the user to change training objects14. Thequick release coupling20 preferably includes aring22, button or the like which may be slid or moved to release the training object from the distal end of thetubular member14. Thetraining object14 preferably includes astem24 secured to the training object via threadedstud26, adhesive28 or the like. Thestem24 is generally constructed and arranged to cooperate with thequick release coupling20 to create an operator securable connection and release. Afiller cap28 may be secured to or formed as portion of the quick release to facilitate access to thelumen18. In a preferred embodiment, the filler cap cooperates with a threadedterminal32. The threaded terminal includes asleeve34 which cooperates with the outer or inner surface of the tubular member for attachment thereof. Afastening device16, such as acarabiner17, hook or the like is secured to an opposite end orsecond end38 of thetubular member14 to allow the person training to secure the second end of the tubular member to a fixed object. In operation, an individual would secure thecarabiner17 to a fixed object. Afterwards the trainee can simulate throwing, pitching or catching the ball. The additional weight of the hollow tubular member helps to strengthen the muscles associated with throwing, pitching or catching the ball. The carabiner secures the hollow tubular member to a stationary object so that it will not fly around when in use. Also, securing the training device to a stationary object prevents the training object from being thrown away or hitting another individual. The trainee can alter the properties of the tubular member by adding or deleting fillers within the tube.

Referring toFIG. 3A, a cross sectional view illustrating thehollow tubular member12 partially filled with afiller material13 for modifying the properties of the tubular member. The preferred substance is a granular material characterized by a loss of energy whenever the particles collide such as sand. However, other substances can be employed, such as lead shot, BB's, crushed shells, crushed gravel and the like. Other suitable materials include materials suitable for absorbing energy, some of which may be released by causing a secondary motion in the tubular member, examples include, but should not be limited to, rubber chunks, springs, water, and other fluids. The only criteria for thefiller materials13 are that they can generally flex and/or conform to the shape of the lumen within thehollow tubular member12.FIG. 3 illustrates thehollow tubular member12 being filled withsand40 andrubber42. The amount of the substance utilized in the present invention depends on the additional weight and type of action resulting from movement an individual wants to add to the training object. Thehollow tubular member12 can be completely empty, partially full, or completely full offiller13. While the preferred embodiment of the hollow tubular member is flexible and non-elastic, it can also be made from an elastic material whereby all or portions of the tubular member are allowed to elastically expand or stretch.

While subject to the trainee's preferences, when the training object is relatively small, such as a baseball or a softball, the amount offiller13 added to the hollow tubular member is relatively small. When the training object is relatively large, such as a basketball or soccer ball, the amount offiller13 added is relatively large. For example, when a basketball is utilized the individual will simulate shooting the basketball or passing the basketball. The repetitive throwing or handling motion of the training object results in an increase in the strength of an individual performing these motions. Additionally, the amount offiller13 in thehollow tubular member12 can be increased as the individual progresses in their training. This will present additional resistance during the training sessions and lead to an increase in strength. This is similar to adding weights to certain exercises in weight training.

While the preferred embodiment illustrates a baseball as thetraining object14 utilized with thetraining device10, other objects can also be employed. For example, a softball, a basketball, a soccer ball, or a football. Additionally, objects such as a straight bar, a curved bar, or a handle can also be secured to the hollow tubular member. These additional training objects can be utilized to develop specific muscle or muscle groups related to tennis, golf, racquetball, baseball or any other sport which requires the player to swing an elongated instrument.

Referring toFIG. 5, a perspective view of an alternative embodiment of the present device is illustrated. In this embodiment, thefirst end36 of thetubular member12 is secured directly to thetraining object14, illustrated herein as afootball44. Attached to thesecond end38 of the tubular member is ahand grip46 andswivel48. Also in this embodiment, the swivel is removably secured to the second end of the tubular member to allow the lumen of the tubular member to be filled to alter its workout properties as described above. Thehand grip46 provides the ability for a second person to provide motion or tension to the tubular member for additional training.

Referring toFIG. 6, a perspective view of an alternative embodiment of the present device is illustrated. In this embodiment, thefirst end36 of thetubular member12 is secured directly to thetraining object14, illustrated herein as agolf club shaft50. Attached between thefirst end36 of the tubular member and thegolf club shaft50 is auniversal swivel52. The universal swivel is constructed and arranged to flex in a polyaxial manner as well as swivel in a planer manner. The universal swivel is removably secured to thefiller cap28 of the tubular member to allow the lumen of the tubular member to be filled to alter its workout properties as described above. Acarabiner17 is secured to thesecond end38 of the tubular member for securing the tubular member to a fixed object. It should be noted that while a golf club shaft is illustrated, a baseball/softball bat, tennis racket handle, racquet ball racket or the like having a substantially rigid elongated shaft with ahand grip56 mounted at a distal end thereof may be utilized without departing from the scope of the invention.
